Hello Everyone, I'm using the Live Streaming Video through WebCam. It's storing in .avi format. When i'm playing the Video. I'm not getting the audio of that video. I hope that opencv does not provide the audio features. Kindly let me know if you have any idea. Thanks,

Please find the below code:---------------

import os.path

import numpy as np

import cv2, time

import random

def change_res(cap, width, height):

cap.set(3, width)

cap.set(4, height)

#Standard Video Dimensions Sizes

STD_DIMENSIONS = {

'480p': (640, 480),

'720p': (1280, 720),

'1080p': (1920, 1080),

'4k': (3840, 2160),

}

VIDEO_TYPE = {

'avi':cv2.VideoWriter_fourcc(*'XVID'),

'mp4':cv2.VideoWriter_fourcc(*'XVID'),

}

def get_video_type(filename):

ext = os.path.splitext(filename),

if ext in VIDEO_TYPE:

return VIDEO_TYPE[ext]

return VIDEO_TYPE['avi']

def get_dims(cap, res='480p'):

width, height = STD_DIMENSIONS['480p']

if res in STD_DIMENSIONS:

width, height = STD_DIMENSIONS[res]

change_res(cap, width, height)

return width, height

#--------------START LIVE VIDEO----------#

random_id = random.randint(10000,99999)

livevideo_name = str('livevideo_'+str(random_id)+'.avi')

frames_per_second = 20.0  #..Frame Per Second

my_res = '480p'  #..Frame Size

# Capture video from camera

livevideos = '/livevideos/'+livevideo_name

cap = cv2.VideoCapture(-1)

dims = get_dims(cap, res=my_res)

video_type_cv2 = get_video_type(livevideos) 

# Define the codec and create VideoWriter object

fourcc = cv2.VideoWriter_fourcc(*'XVID') # Be sure to use the lower case

out = cv2.VideoWriter(livevideos, video_type_cv2, frames_per_second, dims)

while(True):

ret, frame = cap.read()

if ret==True:

frame = cv2.flip(frame,1)

# Write the frame into the file

out.write(frame)

cv2.imshow('frame',frame)

if cv2.waitKey(1) & 0xFF == ord('q'):

break

else:

break

# When everything done, release the video capture and video write objects

cap.release()

out.release()

# Closes all the frames

cv2.destroyAllWindows()
